Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103142, here are decompositions:

19 + 103123 = 103142
43 + 103099 = 103142
73 + 103069 = 103142
211 + 102931 = 103142
229 + 102913 = 103142
271 + 102871 = 103142
283 + 102859 = 103142
313 + 102829 = 103142

Showing the first eight; more decompositions exist.
